Guys I have important (well important for me I guess

) question. My internet connection is limited to 24 GB per month, which means the 10 GB patch is something I can´t really afford. However I am able to download it on a different computer. Now, two questions: Is it possible? I mean, will it work if I just copy it into my Witcher 2 folder? Second question: Do I need to install the Witcher 2 on the machine I will use to download the patch? (It´s not a problen, but if it isn´t necessary it would save me time)
